WATER ELEVATOR.

Application filed September 22, 1921. Serial No. 502,399.

To all whom t may conce/m:

Be it known that I, Onn I. PinnsoN, a citizen of the United States, residing at Inglewood, in the county of Los Angeles and State of California, have invented new and useful Improvements in Tater Elevators, of which the following is a specification.

This invention relates to a water elevator and has for its object to provide a novel construction whereby buckets or other suitable receptacles will be fastened on an endless chain and guided downwardly and upwardly within a well hole. It is the general arrangement of the parts in the operation of the same that will make a high overall efficiency of my improved water elevator. More speeilically, the objects are to provide an improved link chain construction for supporting the buckets; an improved guide member for suitably guiding` the buckets within the well and also an iniproved well casing` in which the buckets are mounted.

Other objects and advantages will be seen and the invention readily understood from the following description of the accompanying drawings in which: j

F ig. l is a vertical section of the well casing and showing the elevator in front elevation.

Fig. 2 is an enlarged fragmentary sectional view of the buckets mounted upon the chain and guide roller taken on line 2-2 of Fig. 1;

Fig. 8 is a fragmentary vertical section taken on line 33 of Fig. 1.

Fig'. 1 is a horizontal section. of the subchamber taken just above the bottom thereof.

Fig. 5 is a horizontal section taken on line 5--5 of Fig. 1.

Fig. 6 is a perspective of the well casing and the opening leading from the water stratum to within the casing.

Fig. 7 is a plan view of the elevator.

Fig. 8 is a section taken on line 8-8 of Fig'. 2.

Fig. 9 is an enlarged fragmentary detail section taken on line 9--9l of Fig. 8.

Fig. 10 is an enlarged fragmentary section of one of the steps leading down within the well and taken on line 1.0-10 of Fig'. 1.

My improved 'elevator 1 is shown mounted within a concrete well casing 2, and terminates in a sub-chamber 3 and a suitable opening` d is formed in the walls of the casing 2 above the sub-chamber 3, and this opening is positioned in the water bearing stratum 5. The opening comprises supporting members 6, spaced apart with a screen or other suitable construction 7, that will allow water to flow through and yet keep sand and dirt out of the well hole 8. vertically mounted withinthe well hole 8 is a rectangular guide structure 9 formed by angle irons 10 positioned at the corners and havingI a suitable lattice work 11 connecting each of the angle irons so as to suitably support` the same throughout the entire length of the hole 8.

rIhe lower ends of the vertical members which extend in right linesto the bottom of the well hole are supported upon a base 12 embedded within a foundation 13 formed in the bottom of the sub-chamber. The guide structure can be rigidly supported within the hole 6 as by having angles 14 spaced at different intervals along,` the casing 2. The upper end of the guide struc ture terminates within cross supports 15.

Mounted above the hole and in alinement with the guide supports, is a wheel 16 moimted upon a shaft 17, which is suitably journaled upon the upwardly extending portion of the casing 2, and any suit able means such as a gear or pulley 18 may be mounted upon the outer end of the shaft so as to rotate the same.

The wheel 16 is adapted to support the elevator buckets and to actuate the same as will be presently described.

rIhe improved link chain construction for supporting the elevator buckets 19, coinprises sets of links 20 and 21 which are pivotally mounted at their ends in cross rods 22 and the buckets have rearwardly extending lugs 23 adapted to engage rods 22. rIh-e ends of the links 20 and 21 have ol'lset portions 24 so as to lit upon the outer side of the inwardly extending portion 25 of the adjacent links, which are mounted upon a bushing 26 surrounding the outer end of the rods 227 and to keep the pairs of links of the respective sets apart, a suitable spacing member 27 is mounted upon the bushing 26 betweenV the portions 25 of the links and a counter pin 28 may be passed through the end of the rod so as to hold the links close to the buckets. It` will thus be seen that the links of the chain will slide ably engage the inwardly extending lflanges 29 of the angle irons 10, and the wheel lil having` notches 30 to engage the rods 22 will cause the chain and buckets to be carried upwardly and downwardly along the angle irons. As the chain is endless, it is necessary to provide a suitable guide means for the return of the elevator on the lower portion of the guide supports, and such means comprises a curved portion 3l, connecting the flanges 29 of the opposite angle irons and the flange portion below the curve will necessarily have to be shaped so as to allow the chain to pass therebetween from the vertical flange around under the curved member 3l.

The return of the elevator takes place within the subs-chamber 3, so it will be seen that there is a continuous lev-el of water well above the sub-chamber 3, due to the opening t being positioned above the same. Any suitable means for causing the water to be emptied from the buckets can be employed and is here shown as com arising a chute 32 leading away from one side of the elevator.

As it may sometimes be necessary for a person to go down within the well for making repairs or any other reason, suitable steps are fixed upon the entire length of the guide structure. These steps comprise substantially U shaped members, having` the projecting portions fixed within the outwardly extending flanges of the angle irons l0, as by a swaged head 8a, and the mentioned angles let may secure the entire structure without interfering with the operation of the chains or buckets.

ln the operation, it will be seen that the buckets mounted upon the chain which has engagement with the wheel 16, will pass downwardly on one side and upwardly on the other side when the wheel is rotated by on the opposite side, the water will be emptied into the chute 32. It will thus be seen that the operation can be continuouslyr carried on.

Various changes may be made in the details of construction by those skilled in the art without departing from the spirit of my invention as set forth in the appended claims.

l claim as my invention:

l. A water elevator comprising in combination a well, a tower supported therein from the bottom comprising a structure with vertical angle members at the corners and cross members joining the angles, a wheel at the top of the tower, an endless chain passing over the wheel down one side of the tower and up the other, buckets on the chain, and means to operate the wheel.

2. A water elevator comprising in combination a well, a tower supported therein from the bottom comprising a structure with vertical angle members at the corners and cross members joining the angles, a wheel at the top of the tower, a stationary curved guide at the base of the tower, an endlessl chain passing over the wheel down one side of the tower around the curved guide and up the other side of the tower, buckets secured to the chain, and means to rotate the wheel.

3. A water elevator comprising in combination a well, a tower structure therein mounted on a base comprising vertical angles forming the tower corners, a lattice work between the angles and forming therewith a channel on opposite sides of the tower, a shaft at the top of the tower, a wheel mounted on the shaft, an endless chain passing' over the wheel down the channel at one side of the tower and up the channel at the other side, buckets mounted on the chain, and means to operate the shaft.

4. A water elevator as claimed in claim 3 having in addition a curved guide at the bottom of the tower between the opposite channels.

In testimony whereof l have signed my name to this specification.
